Description
Left trunk lock for PEUGEOT 307 CC. With functional microswitch 8484L3.
Replace a worn or faulty left trunk lock with this direct-fit unit designed for the Peugeot 307 CC. This locking assembly includes a working microswitch (8484L3) that communicates the latch status to the central locking and interior electronics. Ideal for professional workshops and competent DIYers, the part matches original fitment and restores reliable trunk locking, preventing water ingress, rattles and central locking faults. Customers frequently search by reference numbers 9651004680, 8484Z2 and 8484L3—include these codes when ordering to ensure correct part selection.

Installation Recommendations
Disconnecting the battery is recommended before starting to avoid unintended electrical signals. Access the lock from inside the trunk by removing the trunk lining or access panel. Remove the retaining bolts, unclip the electrical connector for the microswitch and carefully withdraw the old latch. Fit the new lock, secure with the original fasteners, reconnect the microswitch connector and test operation of the latch and central locking from both the key fob and interior release. Check alignment of the striker and adjust if necessary to prevent binding. Apply a light spray of suitable lubricant to moving parts and retest for smooth operation.
Why This Part Fails Most Often
Trunk locks commonly fail due to mechanical wear, corrosion from moisture ingress, or broken internal plastic components after repeated use. The microswitch can stop registering closed/open positions because of contamination, contact wear or wiring fatigue, which results in the central locking failing to recognise the trunk state. Impact damage to the boot lid, misaligned striker, or persistent water leaks accelerate wear and cause intermittent locking or rattling.
Practical Notes For Mechanics and DIYers
This lock is a direct replacement designed to restore factory operation. Verify the connector type visually against the vehicle’s existing harness before installation. After fitting, confirm that the trunk lid closes securely, that the central locking cycles the latch properly and that the microswitch signals correctly (interior light/central locking behaviour). If problems persist after fitment, inspect the striker plate and surrounding seals for damage or misalignment.
